SY Cable containment

to say it meets no standard is not quite fair. There is a makers specification,  and consider Eland's example, made to VDE0250 and tested to a few  other relevant standards as listed in that datasheet. The problem is twofold, DIN  only standards are not 'harmonised' - it would need to be a  "DIN EN" rather like "BS EN", so the standards are German only,  (which has implications for who can test it and what 'sign it off' means in other jurisdictions ) and that in the makers data sheet, the braid resistance is not guaranteed.

But it is certainly not made to a random uncontrolled recipe.

Given that it is a well-established specification with national standards that are relatively stable for a product that is de facto used (and abused) widely beyond those standards' jurisdiction... do we know why CENELEC haven't adopted them to be ENs?

Surely there is a call for it, manufacturers would benefit, and presumably not a lot of work if it is adopting existing documents! So there must be a reason...?

Politics I suspect, because the process is, that following the decision of the European Council, new EN standards must be adopted and implemented immediately and without changes in the member states, and, at the same time, the corresponding national standards get withdrawn. Do not underestimate the no of man hours involved in a pure administrative task like translating DIN documents into French. But I agree, some rationalising is long overdue. The same is true of NYM-J and a few others. (NYM..    NYY)

Politics is always the trouble Mike. SY and YY are widely used in Germany, the French like flexible conduit! There you are at once, Non, non, non! SY in the UK is made to BS6500, similar to all out flexible cables, so where is the problem? I know, they cannot agree the braid wire size and type! LOL!

To be honest even if it was a private standard - if only such and such a maker stated their braid is so many ohms per hundred metres and so many strands of diameter dd or an I2t fusing figure of the braid stranding and or a degree of optical coverage it would be a lot easier - we could then just specify use cable from such and such's .
